Inclusion Criteria

Participants from different groups are measured.
1) Bilaterally fitted CI patients (N=15): CI fitting on both sides.
2) Bimodally fitted CI patients (N=15): asymmetrical hearing loss, with the contralateral side to the CI having moderate or profound hearing loss and fitted with a hearing aid
3) CI-supplied SSD patients (N=15): the contralateral side to the CI has normal hearing (SSD = single sided deafness)
4) Normal hearing participants as control group (N=15).
Participants with CI are postlingually deafened (after language acquisition) and have been wearing the CI for at least one year.

Exclusion Criteria

Patients with neurological damage and pathological, mental limitations are excluded from the examinations; the same applies to patients who take medication that affects the central nervous system

Primary Outcome Measures
NameTimeMethod
Differences were found between the different CI users (bimodal, bilateral, unilateral deaf). The CI group with the greatest amount of cross-modal reorganization and the strongest audio-visual interaction was identified. Important insights into cross-modal plasticity in CI users were obtained and further explanatory approaches are presented to better understand the variability in speech understanding with CI.
